You can also leave it as you have it and setup a src-nat on router b (and a, for that matter) so that traffic to the radio ip is source natted to the router's iface /29. Then the gateways don't matter and whichever end is up will advertise the prefix and either radio is accessible.

What I've been doing... and how it doesn't work:I've been setting up OSPF links using a /29. Router A -- Radio A ~~ Radio B -- Router B Devices get addresses:.1 - Router A.2 - Router B.3 - Radio A (Gateway set to .1).4 - Radio B (Gateway set to .2).5 - Spare (used when swapping links).6 - Spare (used when swapping links)This feels very clean, and works nicely when the link is up or when there is no network loop. However, when the link goes down, if I am connected near Router A, all traffic for that /29 is routed through Router A, and I have no access to the B side. Then, I can only access the B side if I connect closer to Router B. Suggestions? Thanks - Chris
